The Initial Public Offering (IPO) of National Stock Exchange (NSE) has positioned it among India's most valuable companies and cemented its status as the country's largest exchange by market capitalization. Valued at ₹4.45 trillion at the time of listing, NSE was twice as expensive as the combined market capitalization of BSE, Multi Commodity Exchange (MCX), and Indian Energy Exchange (IEX).
The combined market value of these three exchanges amounted to ₹2.28 trillion. At 10 am, the market capitalization of BSE was valued at ₹1.31 trillion, MCX at ₹86,875 crore, and IEX at ₹9,973 crore.
On the debut day, NSE shares traded at ₹1800, which was 0.84 percent higher than the IPO price of ₹1785. According to Vinita Bolinjkar, Head of Research at Ventura, this valuation reflects NSE's dominant position in the market, high profitability, and network-based business model.
Bolinjkar noted that compared to competitors like BSE, MCX, and IEX, NSE operates a broader ecosystem of multi-active exchanges, covering stocks, derivatives, currencies, debt, clearing, indices, data services, and technology solutions, giving it an advantage.
Harshal Dasani, Business Head at INVasset, pointed out two aspects to watch on the first day of trading: the maintenance of thin retail volume and the purchase of the remaining order book by institutional investors in the secondary market.
NSE is also India's largest exchange by trading volume, accounting for 92.99 percent of the cash market turnover for the financial year 26, 99.79 percent in stock futures, and 74.71 percent in stock option premiums.
How should investors approach the exchange business?
Dasani believes that exchanges function like toll roads for activity, making them the best business model in the financial services sector while being the most cyclical. Revenue is generated by two factors: trading volumes and commissions. Volume depends on the market cycle, whereas commissions are largely determined by regulators.
Dasani suggests viewing the exchange business through three lenses. First, regulatory risks must be monitored. Changes in derivative lot sizes or trading fees can affect stocks more than quarterly earnings. He cites the example of IEX: its 85 percent market share is being re-evaluated as regulators move towards market convergence, lowering its valuation to 21 times earnings compared to nearly 50 times for competitors.
Second, one should support shareholders rather than active traders. In his view, at such a scale, growth is often achieved by capturing market share. He points out that BSE's profit grew by 62 percent in the June quarter, while NSE's profit declined by 15 percent for the financial year 26.
Third, valuations should be viewed as a bet on volumes. BSE and MCX, trading at multiples of 48–53 times earnings, require sustained activity growth to justify these ratios. The listing of NSE at around 43 times earnings for the financial year 26 could also set a benchmark for the sector.
He concludes that 'this structure suits patient capital that builds positions for a cycle, not for a quarter, and views every regulatory consultation document as a real income event.'
